China's Tianzhou-3 cargo spacecraft has successfully docked with the space station Tianhe core module.
中国天舟三号货运飞船已成功对接空间站天和核心舱。
It's carrying nearly 6 tons of supplies for the upcoming Shenzhou-13 crewed mission.
它为后续神舟13号载人飞行任务运送了近6吨的补给物资。
This is the second Tianzhou supply run to the orbiting module following the first one back in May.
这是天舟第二次对轨道舱执行补给任务，第一次太空补给是在今年的5月份。
Both cargo ships are now docked with Tianhe and awaiting the arrival of the Shenzhou-13 crew members.
两艘货运飞船现在同时停靠在天和核心舱，等待神舟13号机组人员的到来。
Tianzhou cargo ships have been delivering all kinds of supplies to China space station, from food to clothes, including space suits.
天舟货运飞船一直在向中国空间站运送各种物资，从食物到衣服，也包括宇航服。
They are like delivery men on earth, but space carriers are faster, more efficient and more reliable.
它们就像地球上的快递员，但货运飞船速度更快、更高效、更可靠。
Space engineer Jia Dongyong says Tianzhou cargo ships now hold a world record.
太空工程师贾东永表示，天舟货运飞船现在保持着一项世界纪录。
One of the best ways to evaluate a carrier spaceship is the ratio of load to total weight, the more the payload, the better.
评价货运飞船的最佳方法，就是看装载量与总重量的比率，也就是装载量越大越好。
Now Tianzhou weighs 13.5 ton in total and can carry 6.5 ton of payload. That's the ratio of almost 0.48.
现在天舟货运飞船总重量为13.5吨，装载量可达到6.5吨。比率接近0.48。
The more in cargo ship carries, the more cost efficient it is, and the more it can contribute to space exploration.
货运飞船运载的货物越多，成本效益就越高，对太空探索的贡献也就越大。
For example, if Chinese scientists want to do some large scale experiments, they can deliver the equipment by cargo spacecraft.
举个例子，如果中国科学家想做一些大规模的实验，他们就可以通过货运飞船运送设备。
And the packing process inside the carrier ship follows tested scientific rules.
货运飞船内部的打包过程是经过科学检验的。
Packages are laid out in a way to guarantee balance. Heavier objectives generally go into the section below.
包裹的放置方式保证了平衡。较重的物体通常会放进下面的部分。
We also want them to be easily accessed by astronauts. So for example, things I will be used first I packed last.
我们还希望宇航员能够很容易地拿到物品。所以我会将先用到的东西最后打包。
So just like Tianzhou cargo ships are uniform in shape, they are also uniform in being reliable and efficient.
因此，就像天舟货运飞船在外形上是统一的一样，在可靠性和效率方面，它们也是统一的。
